France 3 Claims.

My invention relates to means for suspending bombs from aircraft and for releasing same, the device being actuated by the explosionA of a power charge ignited by an electrical current.

5 In the drawing affixed to this specification-and forming part thereof a device embodying my invention is illustrated diagrammatically by way of example.

In the drawing:

Fig. l is a vertical axial section,

Fig. 2 a horizontal section view.

Referring to the drawing, |36 is an apertured metal sleeve suspended from a support |35' 4xed to the fuselage of an aircraft or the like and with a ball suspension |52 formed at .the top of a connecting piece |35, the sleeve |36 being thus enabled to always retain its horizontal position. |32 and |32 are two eyes xed to the connecting piece |35 and |3| is a pin supported in the two eyes and serving to have a bomb attached to it,

which is then suspended between the eyes |32, |32. The pin |3| is xed to a barrel |33 mounted in the left hand half of the sleeve |36 for axial reciprocation against the action of a coil spring |40, the outer end of which rests on .the stopper |53 closing this end of the sleeve |36. The spring |40 encircles a piston |38 xed in the stopper |53 and extending through a bore' in the bottom of the barrel |33, the enlarged head |39 of the pis-A ton. itting the boring of the barrel 'and resting against the barrel'bottom, whenA the barrel is acted upon by the pressure of spring |40. This latter embraces another piston |34 fixed in the member forming the eye |32, this piston being formed with an axial conduit |54 and, at its inner end, with a larger bore |55, in which is seated an insulated metallic sleeve |49. Into this sleeve and through the bore |54 of the piston |35 extends the conductor |50 which also passes 40 through an axial bore in the connecting piece '|35 andle'ads to an electrical switching device (not shown) of a suitable kind.

In the bore |42 of barrel |33 is mounted a cartridge containing a powder charge |42' and a spark plug |43, the rear face part of the cartridge being closed by an insulating stopper |45 trav'- ersed by a metal pin |46 connected at one end to lthe igniting device |43, which is in its turn connected tothe cartridge case, and at the other end to the conductor |50. y

At the right-hand end the sleeve is closed by a stopper |56, which is traversed by a rod |31 xed in the member forming the eye |32' and Y the enlarged head |31" oi.' which rests on the u outer tace of the stopper |66. A coil spring |4|- Application April 1, 1936, Serial No. 72,135 Y l lin France July 9,1935

(Cl. Sil-1.5)

tends to hold the head l31.applied against the stopper |56. A

.On the igniting circuitbeing closed, the spark formed at |33 will ignite the charge |62 and the explosion gases will drivethe head |39 of piston 5 |38 together with the vbarrel 33, into which this piston extends, to the left, the sleeve |36 being carried along by these parts and being displaced relative to the piston |34 and the eye members |32, |32'. The suspension pin |3| being xed to the piston |34 is thereby moved to the left, leaving the eye |32 and sliding in the eye |32, whereby the bomb suspended from the pin |3| is released and allowed to,drop. When the sleeve |36 has reached the end of its course, wherein the stopper |56 closing its right-hand end meets the outer end of the sleeve |31', the barrel |33 will continue moving towards the left, compressing spring |40, until the barrel abuts against the buier ring |36. At this moment an aperture |64' formed in the wall of the barrel |33 is uncovered and allows the powder gases to escape and the cartridge case to be thrown out. 'Ihe springs |40 and |4| thenreturn the barrel |33 and the sleeve |36 into their initial positions.

In order to introduce a new cartridge, the barrel |33 is shifted towards the left by means oi' a laterally projecting handle |46 (Fig. 2) and in carrying along the sleeve |36 renders its interior accessible through the aperture |44.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and describedfor obvious modifications will occur to a person skilled in the art.

I claim:

1. A bomb release device for an aircraft which comprises, in combinatioma piston adapted to be ixed rigidly to said aircraft, a barrel fitting on said piston movably with respect thereto, a sleeve surrounding said barrel slidably with respect thereto,' a part rigid with said piston forming a l housing for the suspension ring of a bomb, a supporting pin for said ring rigid withsaid barrel and slidable in said housing, said barrel being provided with a chamber opposite the end of said piston adapted to receive a load of powder, ignitlng means for said load operative from the outside of said barrel, a rod rigid with said sleeve having a head tting in said chamber so as to close one end thereof opposite said piston end, 50 an abutment carried by said head adapted to cooperate with said ban'el for driving it outwardly when said load is ignited.' at least one spring interposed between the corresponding ends o! said barrel and said sleeve-an abutment vcarried comprises, in combination, a piston adapted to be secured to said aircraft, a barrel fitting on said piston movably with respect thereto, a sleeve surrounding said barrel slidably with respect thereto, a part rigid with said piston forming a housing for the suspension ring of a bomb, a supporting pin for said ring rigid with said barrel and slidable in said housing, said barrel being provided with a chamber opposite the end of said piston adapted to receive a load of powder, igniting means for said load operative from the outside of said sleeve, a rod rigid with said sleeve having a head tting in said chamber so as to close one end thereof opposite said piston end, an abutment carried by said head adapted to cooperate with said barrel for driving it outwardly when said load is ignited, whereby both said sleeve and said barrel are caused to slide with respect to said piston by the explosion of said load, spring means interposed between said sleeveand said piston for resiliently opposing this displacement, an abutment carried by said piston for stopping the movement of said sleeve with respect to said piston after a predetermined displacement, whereby said barrel is subsequently caused to slide alone with respect to said sleeve, spring means interposed between said barrel and said sleeve for resiliently opposing this last mentioned displacement, and an abutment for said barrel carried by said sleeve for stopping the movement of said` barrel with respect to said sleeve.
